IMPRCVEMENT IN TURBINE WATER-WHEELS.

Specification forming part of Letters Patent No. 165,334., dated July 6, 1875; application filed March 23, 1875.

To all whom it may concern:

Be it known that I, STEPHEN R. J ENNER, of Milltown, in the county of Crawford and State of Indiana, have invented a new and Improved Turbine Water-Wheel; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing forming a part of this specification, in which- Figure l is a vertical section with turbinewheels in side elevation; Fig. 2, a detail, showin g the relation of the stationary water-ways to the buckets of the alternating turbinewheels.

The object of this invention is to utilize a larger per eent.ot' motive power than is usually obtained in common turbine-wheels, and to render the same more constant and uniform in their action. It consists in placing stationary water-ways in between two or more turbinewheels attached to the shaft, the said waterways being detached from the shaft, and alternating with the turbine-wheels, and the ways running in direction transversely to the spiral flanges of the turbine-buckets. It also consists in the combination, with the stationary waterways and the turbine-wheels, of a cylindrical cutoff and a counter-balance, as hereinafter more fully described.

In the drawing, A represents an ordinary turbine-wheel, having revolving buckets a and inlet water-ways b. B is a second turbinewheel at the opposite end of shaft, having its buckets arranged to turn in the same direction as the first. Both these wheels are rigidly attached to a shaft, 0, which revolves upon a bearing, 0, supported by the pieces D, which are attached to the incasing-cylinder E. F is one of the stationary water-ways placed between the two turbine-wheels A and B, the said ways being arranged transversely to the spiral flanges of the buckets of the turbinewheels, so that they deliver the volume of water received from the first wheel full upon the buckets of the second, thereby utilizing a large amount of power that would otherwise be wasted.

I do not confine myself to one stationary set of water-ways arranged between two revolving wheels, but I may place a number of them upon the same shaft, and have them alternate with revolving wheels, as described.

G is a cylindrical cut-ofi' to regulate the flow of water from the inlet water-ways b to the turbine-wheels. Said cut-ofi' is arranged to slide vertically between the outer casing E and the outer surface of the stationary water-ways, and is maintained upon supports H, attached to the movable collar I of the centrifugal governor. J is a lever, having bifurcated ends, in which. are pivoted the studs d, attached to the sliding collar I. Said lever is pivoted at K upon a support, and is attached by means of a link to a graduated lever and weight, K. The object of this mechanism is to counterbalance the weight of the cylindrical eutofl', and render the cut-off sensitive to the action of the governor.

Having thus described my invention, what I claim as new is- 1. The combination, with two or more turbine water-wheels attached to one and the same shaft, of alternating stationary waterways, which deliver their water transversely to the inclination of the turbine-buckets, substantially as and for the purpose described.

2. The combination, with the turbine-Wheels and the alternating stationary water-ways, of the cylindrical cut-off G, the lever J, and the weight K, substantially as and for the purpose described.
